I'm not going to mince words here - I get to be blunt for a change, it's Father's day! (Heh, yeah, that'll work...)
1) I'm partial to short descriptions myself. I also am a stickler for rules. So I see this as you do, Brar. But the way you kicked off this topic screamed to me your position and implied to me that you want something done about it. It did not come across as opening up a discussion, it
did sound accusatory toward anyone with a longer description. Why not just say "I have to play on a small screen and have recently run into some very long descriptions which I really don't like. What should I do? Am I within my rights to OTELL the author this? Is it likely to do nothing other than hurt their feelings?" Or maybe even just a post explaining what is hard about long descriptions for you - something you have laid out well, but with a lot of loaded language piled on top of it. Most players, if they understand how it is problematic for you, will adjust their own habits. The description guidelines were put in place for good reason, but many have forgotten what they are, or (mistakenly) think them inconsequential in the modern era of 21" monitors.
2) The time and energy of the upper echelons of this game's management is limited. Complaints go to the very top. Do we really want them spending their time dealing with a complaint about something like description lengths? I humbly ask everyone to solve as many problems as they can at the most local level possible - in this case, by discussion between players, be it on the forums or in-game. If you really can't resolve it yourself (and alas, that is inevitably the case with many things related to code) and it is important, by all means use the complaints or applications processes. But don't make them your first recourse in all matters, especially those you may be able to solve yourself! (This is intended as an answer to Brar's question about the appropriateness of filing a complaint about description lengths - I'm saying I really don't think it is the way to go, not because you have nothing to complain about, but rather because you should not have to turn to the Imms for something like this...and frankly, if that was the only fix that would work, I'd choose instead to live with it.)
3) As a helpfile editor, I'm sure I'm guilty of writing overly long helpfiles, too. I can tell you the top brass is on the side of those with small screens, as I get chided for helpfiles that are more than 20-some lines. But the way around it is less detailed information, or (with helpfiles I at least have this option) links to additional helpfiles. Problem is, the latter take a lot more time and editing. People often want more detailed information, and they don't want to have to wade through a menu system to get it. But based on my experience with helpfiles I would encourage folks with long descriptions to ask themselves these questions:
a) Can you prioritize the content, as in a newspaper article? Your adjective on the first line, a brief description on the next few, and then a detailed description, if you must include such? I've seen this done beautifully, with "Upon closer inspection, you notice..." and segues of that sort. This isn't as helpful to Brar and others as a truly concise description, but it is helpful nonetheless. I get hot under the collar when someone asks "Didn't you read my description? It's right there on line 67, after the dragon tattoo and before the purple eyebrows - I'm missing my left ear!"...usually after they chide me for taking more than 10 seconds to reply to their question about their earrings (I was trying to read their description), upon meeting them the first time.
b) Is everything you are saying in your description really visible? I cough a bit at the "[When he is naked, you can see] a roaring tiger tatoo under his navel" family of description content. I'd rather know your feet smell, really.

That I'm ICly more likely to realistically find out.
c) Were you to bump into yourself in a dark alley, would you really read your entire description? Would you be happy you did? We all love our own words with a certain lack of reason (myself included), so perhaps you should ask someone else, who you can trust to be forthright, about whether you are overdoing it.
That's it, all the bluntness I can manage in one go! I'm not keen on the idea of the Imms laying down the law with respect to description format, even though I'd love to see them all shorter, if not less grandiloquent. (Heck, FK boosts my vocabulary! I'd never have known that bootyliscious and pulchritudinous mean roughly the same thing, were it not for this game and this forum.) They need to be "good," by some modicum of popular view, but they need not fit a boilerplate.
